- ATTORNEY- Patented May 6, 1930 UNITED STATES PATENT OFFICE ARTHUR G. MASON, OI! HAWTHORNE, NEW JERSEY FABRIC-TREATING MACHINE Application filed January 17, 1928. Serial No. 247,311.

This invention relates to apparatus for series of catching portions or hooks and ctreating fabrics in the removal therefrom operating cutting edges, arranged around its of floats left in the weaving. The object of axis and forming its periphery, alternating the invention is to provide means whereby, with each other. Each series of hooks is here I with expedition and without the application formed, as at 9, at the periphery of a :disk 9, 5.

of any particular skill on the part of the each hook projecting in one circular direcattendant, a fabric may be operated upon so tion of such periphery. Each cutting edge is as to part floats existing therein, preferably here formed, as at by beveling and sharpin such manner, as by severing, that such ening the periphery of a disk 10. In the ex- 1 parting will take place in the float itself and ample, one such disk 9 coacts in the parting 60 without drawing on the thread involved in a of the floats with one such disk 10, as will way to produce a blemish in the fabric. be explained, and for this purpose the cutting I th drawings, edge 10" has a d ameter less than that repre- Fig. 1 is a side elevation of the invention sented by the points or free ends but greater shown associated with a fabric shearing than that represented by the bases of the means; series of hooks 9 and, while it lies opera- Fig. 2 is asection on line 22, Fig. l with tively close to the series of hooks, is spaced the working parts illustrated arranged in that therefrom by a slight thickeningsup of the position where they receive the fabric between dlsk 9 to form in effect a hub!) thereon (Figs.

Further, said ele- The f re i ro a y element is pr ment, while it should of course be arranged ably of generally cylindrical form, with so that for its full length its periphery is in otherconsiderations it is best in a practical 1. Supporting means application of the invention for bracket 19 to be adjustably supported, whereforeI provide for its support as follows: A clamp 20 embraces the bracket 19 and has a radial stud 21 projecting therefrom. This stud is longitudinally and rotatively adj ustably held (by a set screw 22) in one sleeve portion of a gimbal 23 whose other sleeve portion is longitudinally and rotatively held (by a set screw 24) 'o n the horizontal supporting shaft 25. Thus the bracket, with. said rotary element and brush, may not only be adjusted along the shaft 25 to any position transversely of the path of travel of the fabric, but the universality of movement afforded by the gimbal permits said element and brush to be set at any inclination or at any degree of obliqueness or at rightan les or parallel to the path of travel of the fa ric, as the circumstances may require.

f course the said rotary float-parting element'is rotated by some means in the proper direction hereinbefore indicated, such means being shown in Fig. 2 as a belt 26, assumed to be suitably'driven, engaging a pulley 27 on the collar 13; this belt may also, through a pulley 28, drive a brush.

Where fabrics are woven in looms having automatic means to replenish'the filling the floats usually occur in each selvage region, in' 'whichcasesit is unnecessary for the floatparting element and brush to have greater longitudinal extent than as shown byFig. 3.

The catching portions 9 are in the present case hooks of the kind that project in one circular direction of the periphery of the float-parting element and are undercut.

Sometimes an edge-float will stand underlapped, i. e., folded or bent back upon that face ofthe fabric which is in the illustration next to the' brush, so that with the parting element alone present such a float wouldes- -cape unparted. Hence the brush constitutes means for sweeping or displacing such floats into a'position in which they are not screened by the fabricbut project laterally outward from its edges within thereach of the parting element.

Having thus fully described my invention,whatIclaim is: f

inwhich the fabric tobe treated is stretched, in combination withaa rotary element ,journaled in said means with its periphery close to the fabric and having at its said periphery a series of 'float-catchingportions extending around its periphery and means, coactive with each such portion, to sever a float when caught thereby.

2. Supporting means in which the fabric to be treated is stretched, in combination with a rotary clement journaled in said means with its periphery close to the fabric and having at its said periphery a series of undercut float-catching hooks extending around its periphery and projecting in one circular direction of such periphery, and means, beside each hook, to sever a float when caught thereby.

3. Supporting means in which the fabric to be treated is stretched, in combination with a rotary element journaled' in said means with its periphery close to the fabric and comprising a series of coaxial disks, alternate disks "having peripheral floatcatching portions and the remainder floatsevering edges'coactive with said portions to sever the floats caught thereby.

4. Supporting means in which the fabric to be treated is stretched, in combination with a rotary element having its periphery close to one face of the fabric and having peripheral means to disrupt threads of the fabric upon said face, said element being pivotally adjustable in substantial parallelism with said face of the fabric.

5. Supporting means in which the fabric to be treated is stretched, in combination with a rotary element having its periphery close to one face of the fabric and having peripheral means to engage portions of the fabric upon said face, and a gimbal support for said element. v

6. In combination with supporting means, coacting means between which the fabric to be treated is adapted to be stretched, one of said means including a rotary substantially cylindrical element having a series of spaced rigid peripheral catching portions to engage projections on the fabric andthe other comprising a rotary core opposed to said element and yielding bristles arrranged around and projecting therefrom and formed as a. substantially cylindrical supportfor the fabric. 7. Supporting means in which the fabric to be treated is stretched, in combination with means, arranged opposite one face of the fabric and projecting beyond the selvage edge thereof, to part floats existing on such face and at said edge, and means to displace edge floats'folded upon the opposite face of the fabric into laterally outwardly projecting relation to such edge and hence into the reach of the second-named means.

8. In combination, with supporting means, coacting means between which the fabric to be treated is adapted to be stretched, one of said means including rigid portions to engage projections on the fabric and the other comprising a rotary core opposed to said oneof said coacting means and yield ARTHUR G.
